Mode K (

)
When the count present value PV counts up or counts down to
the count setting value SV1, Output 1 will turn ON momen-
tarily for the time set in the output pulse width parameter
(
tout1
) or will be maintained ON if the output pulse width
parameter (
tout1
) is set to 0.00. When the count PV counts
up or counts down to the count SV2, Output 2 will turn ON
momentarily for the time set in the output pulse width param-
eter (
tout2
). If Output 1 is ON when Output 2 turns OFF,
Output 1 will also turn OFF. The count PV will continue to
increment or decrement with each input signal.
The leading edge of a “reset” input signal at RST1 will turn
OFF both outputs, reset the count PV to 0 and prohibit an
input signal from incrementing or decrementing the count PV.
The trailing edge of the “reset” signal at RST1 enables counting
to begin.
The “reset” signal minimum pulse width is set by reset pulse
width parameter (
rtSr
) or DIP Switch 8.

Note: T1 momentary ON time set in output

Mode P (P)
When the count present value PV counts up or counts down to
the count setting value SV1, Output 1 will turn ON momen-
tarily for the time set in the output pulse width parameter
(
tout1
) or will be maintained ON if the output pulse width
parameter (
tout1
) is set to 0.00. When the count PV counts
up to the count SV2, Output 2 will turn ON momentarily for
the time set in the output pulse width parameter (
tout2
). The
count PV display is prohibited from incrementing or decre-
menting until the end of the output pulse time (
tout2
) when
both outputs turn OFF and the count PV is reset automatically
to 0 and any input signals that occurred during the output pulse
time.
The leading edge of a “reset” input signal at RST1 will turn
OFF both outputs, reset the count PV to 0 and prohibit an
input signal from incrementing or decrementing the count PV.
The trailing edge of the “reset” signal at RST1 enables counting
to begin.
The “reset” signal minimum pulse width is set by reset pulse
width parameter (
